I'm having to reroof my entire house do to a poorly ventilated roof with osb sheathing and rolled core vent on ridge. It has two hole bird block intake vents at eaves. I have resheathed with 5/8" plywood and ice & water gaurd and plan to install Certainteed Landmark shingles. My question is which ridge vent to use for best performance:
Air Vent Shingle Vent II vs. Lomanco Omni Vent vs. Ridgemaster? Which shingle over ridge vent system exhausts best when balanced with intake correclly? Are the performance claims for the exterior baffle true?
